Coming off of LIMBO, I think PlayDead did a great job with this game. You get the same eerie atmosphere that Limbo provides, but with a lot more detail and opportunities for worldbuilding and subtle storytelling. Puzzles are fun (most of the time), and the game offers you a great sense of progression as you make your way through them and into new locales. And adding new mechanics along the way keeps things fresh, while also lending themselves cleverly as part of the narrative. Although the ending may be controversial, Inside is a great game all the way through.
